  4. 2. Framing Generative Technology for Dynamic Capabilities: A case study of AI platform implementation in large enterprises

    Author : Maria Kandaurova; Chalmers tekniska högskola; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; organizational innovation; framing; generativity; dynamic capabilities; AI; technology implementation; incongruences;

    Abstract : Organizations are increasingly turning to generative technologies known for their inherent dynamic, malleable, and context-agnostic nature to innovate and create a competitive edge. As generative technologies offer virtually unlimited potential applications, organizations are constantly challenged to identify appropriate applications. READ MORE

  5. 3. Scalable Methods for Developing Interlocutor-aware Embodied Conversational Agents : Data Collection, Behavior Modeling, and Evaluation Methods

    Author : Patrik Jonell; Jonas Beskow; Joakim Gustafsson; Gustav Eje Henter; Justine Cassell; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; non-verbal behavior generation; interlocutor-aware; data collection; behavior modeling; evaluation methods; Tal- och musikkommunikation; Speech and Music Communication;

    Abstract : This work presents several methods, tools, and experiments that contribute to the development of interlocutor-aware Embodied Conversational Agents (ECAs). Interlocutor-aware ECAs take the interlocutor's behavior into consideration when generating their own non-verbal behaviors. READ MORE

  6. 4. Towards an Emotionally Intelligent Interaction Strategy for Multimodal Embodied Conversational Agents acting as Companions

    Author : Nena Roa Seiler; Mälardalens högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract :   Existing Human Computer Interaction (HCI) strategies are seriously limited by current technologies. These are neither sensitive nor accurate enough to respond to users’ emotional states, the fundamental basis for effective communication in real time. READ MORE

  7. 5. Developing Multimodal Spoken Dialogue Systems : Empirical Studies of Spoken Human–Computer Interaction

    Author : Joakim Gustafson; KTH; []
    Keywords : Spoken dialogue system; multimodal; speech; GUI; animated agents; embodied conversational characters; talking heads; empirical user studies; speech corpora; system evaluation; system development; Wizard of Oz simulations; system architecture; linguis; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : This thesis presents work done during the last ten years on developing five multimodal spoken dialogue systems, and the empirical user studies that have been conducted with them. The dialogue systems have been multimodal, giving information both verbally with animated talking characters and graphically on maps and in text tables. READ MORE
